In the case of measuring condenser microphone impedance using voltage drop
Try this method shown in a Jensen Tranformer app-note:

That will work for an active output microphone if you measure the impedance of pin 2 reference to pin 1, and separately pin 3 referenced to pin 1, and add the results together.
For a transformer output microphone you would use pin 3 as the reference pin for the signal generator, and connect the measurement resistor to pin 2.
